The reigning U.S. and French Open champion and world No. 1 Nadal took the
first set from Bernard Tomic, 6-4, when the Aussie decided to retire to a
chorus of boos on a hot Day 2 at Melbourne Park.

The 21-year-old Tomic was a runner-up in Sydney last week.

Nadal captured his lone Aussie Open title in 2009 and was the runner-up here
in 2012. He missed last year's edition due to injuries.

Up next for the 13-time major champion will be 17-year-old Aussie Thanasi
Kokkinakis.

Meanwhile, the fourth-seeded and three-time Aussie Open runner-up Murray made
short work of Japan's Go Soeda, routing him 6-1, 6-1, 6-3, while a sixth-
seeded Federer dominated Aussie James Duckworth 6-4, 6-4, 6-2 in 1 hour, 46
minutes at Rod Laver Arena.

Murray lost to Novak Djokovic in last year's Melbourne finale. His second-
round opponent will be Frenchman Vincent Millot.

The Swiss legend Federer, who owns a men's-record 17 major titles and is
appearing in a record 57th straight Grand Slam event, is looking to win for a
fifth time in Melbourne and for the first time since 2010. He was also a
runner-up here to Nadal in 2009.

Asked how he handled the heat on Day 2, the 32-year-old Federer said: "I'm
here. I'm speaking. Actually, it's not crazy. I'm feeling OK right now.

"It was very dry, just hot, stinging sort of sun. Depending on where you come
from it has a bigger effect on you, this type of heat. So it's very personal,
and it can become just a very mental thing -- you just can't accept that it's
hot."

The former world No. 1 Federer's next outing will come against Slovenian Blaz
Kavcic.

Last week's Sydney champion, fifth-seeded Juan Martin del Potro, was a 6-7,
6-3, 6-4, 6-4 winner over American Rhyne Williams. Up next for the former U.S.
Open champ will be Spaniard Roberto Bautista Agut.

Winning the Auckland title last week may have taken too much out of 13th-
seeded John Isner. The highest-seeded American lost the first two sets to
Slovak Martin Klizan, 6-2, 7-6 (8-6), before retiring because of a foot
injury. Isner did not appear in last year's Aussie Open due to a bone bruise
in his right knee.

Fans sat through temperatures that reached well over 100 degrees and
watched local favorite Lleyton Hewitt fall to 24th-seeded Andreas Seppi, who
saved a match point before winning 7-6 (7-4), 6-3, 5-7, 5-7, 7-5. The former
No. 1 Hewitt was making his 18th straight appearance in the event, where he
finished as a runner-up back in 2005.
